I'm not sure if you meant you just wanted to access the information programmatically, in which case somebody else who knows python should respond, but one possibility instead of writing a file is to send the information to the Reply Log. You can do that by specifying the writesel output filename as "-" (just the dash, no quotes).
I wouldn't expect the residues you listed to be considered "ligand" so I opened 2izh and tried it, which just gives me the two BTN residues.

So in my script I'm using the runCommand function to get the info on the ligand, but I'd like a way to do so without writing it to a file.

I'd like to continue the script to sort out through some of this information but I'm dealing with a lot of pdb files so I'd prefer not to have write a file, open it, read it, then rewrite it and repeat a ton of times.
